摘要
针对预应力混凝土管片这一新型的盾构隧道衬砌结构进行了模型试验研究,介绍了利用有限元方法进行模拟计算的过程,采用不同的接头力学模型对其整环试验进行了两维模拟,在与试验结果分析比较的基础上,得出合适的模型参数,为预应力管片用于设计和施工奠定了基础。
Model test is made for a new type lining structure,i.e.prestressed segment of shield tunnel.The whole process of FEM calculation is presented.Two-dimensional FEM numerical simulation was made for the full ring test with regard to different joint stress model.Then,proper parameters were achieved for models based on the comparison of test results,which has laid a solid foundation for the design and construction of prestressed segment.
